    TRUE OR FALSE:IONIC COMPOUND DISSOCIATE WHEN THEY DISSOLVE IN WATER   

    Correct Answer
    TRUE
    Explanation
    Ionic compounds dissociate when they dissolve in water because water molecules surround the ions and pull them apart, breaking the ionic bonds. This process is known as hydration. The positive ions (cations) are attracted to the negative oxygen atoms in water, while the negative ions (anions) are attracted to the positive hydrogen atoms in water. As a result, the ions become surrounded by water molecules and are able to move freely in the solution, leading to the dissociation of the ionic compound.

    IN ORDER FOR NA+ TO BE CREATED. SHOULD ELECTRONS LOOSE AN  ATOM

    Correct Answer
    LOSE ATOM, YES
    Explanation
    The given answer suggests that in order for Na+ (sodium ion) to be created, electrons need to be lost by an atom. This is because sodium has one valence electron in its outermost energy level, and in order to achieve a stable electron configuration, it tends to lose this electron and form a positive ion with a +1 charge. This process of losing electrons is known as ionization. Therefore, the statement "LOSE ATOM, YES" correctly explains the process of creating Na+ ions.

    HOW ARE COVALENT BONDS CREATED

    Correct Answer
    THEY ARE CREATED WHEN ATOMS SHARE ELECTRON, WHEN TWO ATOMS SHARE AN ELECTRON
    Explanation
    Covalent bonds are formed when atoms share electrons. In this process, two atoms come together and each contribute one or more electrons to a shared electron pair. This sharing of electrons allows both atoms to achieve a more stable electron configuration, similar to that of a noble gas. The shared electrons are attracted to both nuclei, creating a strong bond between the atoms. This type of bond is typically found between nonmetals or between a nonmetal and a metalloid.

    AMINO ACIDS ARE JOINED BY WHAT?

    Correct Answer
    PEPTIDE BONDS
    Explanation
    Amino acids are joined together by peptide bonds. Peptide bonds are formed through a condensation reaction between the carboxyl group of one amino acid and the amino group of another amino acid. This reaction results in the formation of a covalent bond, known as a peptide bond, between the two amino acids. This process repeats, forming a chain of amino acids called a polypeptide. Peptide bonds are crucial for the structure and function of proteins, as they determine the sequence of amino acids and therefore the overall shape and properties of the protein.
